“Identity” (post 2) by Nora Roberts: “million personas” of the villain

“Gavin Rozwell had learned early on the female of the species offered almost endless opportunities to exploit and manipulate…He had a million personas he could wear like a bespoke suit…a natural-born psychopath…He knew he killed his mother over and over with the termination of each mark…just the way his father had taken everything his mother had valued” (1, pp. 101-103).

Comment: Where did the author get a villain with a million personas? From a stereotype of serial killers? Or from the antithesis of prolific authors with multiple personality trait?
